- Microsoft Office 365
- G-Suite by Google
Local Network Hosted
installed on the server and then accessed remotely from client workstations
- easier to maintain the software and regulate user access
Cloud Hosted
Software as a Service, or SaaS, provides users with the applications they need to do their day-to-day work thorugh the cloud
One Tier
common programs run as standalone applications on a single computer
- called single-tier, or one-tier, applications
- Include traditional office productivity software and other
programs that don’t require access to a separate data source.
Two Tier
Business applications that store and retrieve data from a central repository typically operate more
efficiently with two separate tiers: a client and a server.
- typically runs a database management
system, like Oracle or SQL Server, which keeps the data secure, organized, and up to date.
Three Tier Architecture Model
Presents the user interface on a client workstation, processes data on an
application server, and retrieves information from a database management system on a database
server.
- Presentation Tier
- Application (aka Logic or middle) Tier
- Data (aka database, data access or back-end) Tier
Presentation Tier
User Tier or interface.
- Web presentation tiers are usually developed using HTML,
CSS and JavaScript.
Application Tier
Logical or middle tier, where data is collected and sometimes processed against
the info in the data tier.
- Typically developed using Python, Java, Perl, PHP or Ruby, and communicates with the data tier usingAPIcalls.
- All communication goes through this layer
Data Tier
database, data access or back-end tier is where the data associated with the
application is stored and managed.
- Can be a relational database management system such
as PostgreSQL, MySQL, MariaDB, Oracle, DB2, Informix or Microsoft SQL Server - Or in a NoSQL Database server such as Cassandra, CouchDB or MongoDB.
N-tier
implies that application developers can theoretically add as many tiers as they need to
create the most efficient services and processes on a network.
Popup Blockers
a feature of most web browsers. It prevents pop-up windows (like advertisements)
from being displayed.
- Web browsers often block pop-up windows to protect you from malware.
Compatible browsers for Applications
If your web browser is not displaying website content properly, consider installing and using a different
web browser.
- Popular web browsers include Google Chrome, Mozilla Firefox, Apple Safari, and Microsoft Edge.
Single Use License
Personal licenses are aimed at home and small business customers.
- A single-use license can be installed on only one computer.
Group Uses/Concurrent License
When purchasing a license that can be used by multiple people for a corporation that may have
hundreds of employees, software vendors let you purchase a group license often for an unlimited
number of uses.
Open Source vs. Proprietary
Open-source software is usually freely distributed.
- means you can download, install, and
use the software without paying a licensing fee. - you can download the source code for an application, modify it, recompile it, and then use the
modified version of the software.
When you purchase proprietary software, you don’t own it.
- Because you’re purchasing only a license and not the software
itself, you’re not allowed to access the software’s source code and make any modifications.
Subscripton vs. One-time Purchase
Users pay a monthly or annual fee to use the software and receive regular updates.
The software is set up to automatically download and install updated versions if the subscription
is current.
- Individuals and businesses can save money up front by not purchasing a perpetual software
license, but they must pay the subscription fee for as long as they want the software.
Product Key and Serial Numbers
The key is obtained after legally purchasing the software and is
usually a string of characters, sometimes printed on the package or electronically sent after an on-line
purchase.
- The product key
generates a unique product ID or serial number. This number is often required to obtain technical support (and indicate the support level).
Reading Instruction/Agreements
Before installing (or buying) an application, the best practice is to always read the
documentation that comes with the software.
- What licenses are required.
- If there are any known issues with the application.
- Whether the application will work on your operating system.
- If the hardware in your computer is compatible with the application's requirements. For
example, some applications require a 64-bit system.
Advanced Options
Often let you change the default location for installing files as well
the options to install.
- This means that you can customize the installation by excluding unnecessary
components or installing additional components not installed by default.
